Switching device and method for controlling a switch

Abstract

A switching device and a method for controlling the switch are provided, wherein a control terminal resistance of the transistor device is set according to an operating condition within a specified range of operating conditions.

Description

technical field [0001] The present application relates to switching devices and corresponding methods. Background technique [0002] Switching devices are often used to selectively electrically couple two terminals of the switching device to each other, for example, to couple, for example, two parts of an electronic circuit. A particular type of switching device is a power switching device, which is used to selectively couple a load to a supply voltage, such as a positive supply voltage, a negative voltage or ground potential. [0003] In electronic circuits, transistors are used in many cases as switching devices, for example field effect transistors such as metal oxide semiconductor field effect transistors (MOSFETs), bipolar transistors or insulated gate bipolar transistors (IGBTs). In some applications, such switching devices must operate over a wide temperature range. For example, IGBT modules in automotive applications such as electric vehicles or traction control ap...

Rapid switching in turn can cause voltage spikes when switching devices

[0005] Furthermore, the blocking behavior of semiconductor devices decreases with decreasing temperature, i.e. breakdown or other events that cause switching devices to conduct current may occur at lower voltages for lower temperatures than for higher temperatures
